Economical and disposable covers provide dust-free storage of clean labware. Foil glassware and flask covers are pre-formed to quickly cover a wide variety of labware using only one hand. Ideal for use in centralized washing areas where cleaned labware needs to be transported back to the lab while remaining clean and contaminant-free. Cover-ALLS™ are autoclavable at 121°C (250°F) and are perfect for providing a temporary, sterile boundary for autoclave sterilization of labware.
